ADSL is a type of DSL that allows you to connect to the Internet using your regular phone lines. The DSL signal is broadcast using frequencies to a central office (CO) that then relays the signal back to the user. These signals are transmitted above the normal voice signals used for telephone service. One of the unique properties of ADSL is that a splitter can be used to allows Internet service and voice calls at the same time. The wireless ADSL modem facilitates these connections and sends the signal from your computer and transmits it. The modem also receives the signal and makes it so that your computer can decode the information.

Benefits of Using ADSL Modem
-
ADSL is different from DSL in that it features much faster download and upload speeds, and also allows for multiple connections to the signal. ADSL also allows for a DSL router to be used. ADSL is widely available in urban/suburban areas, and is much less expensive than cable, while providing comparable upload/download speeds. The wireless modem helps facilitates these fast speeds, and the fact that it is wireless has no effect on speed or efficiency.
Drawbacks of Using ADSL Modem
-
The biggest drawback of ADSL is that if you are not within am eight- to 10-mile radius of the central office (CO), you will not be able to use receive an ADSL signal, which would render your ADSL modem useless. Because ADSL gets it speed from transmitting high frequencies to the CO, if you are too far away, your connection speed will degrade lower than regular DSL. This is especially troublesome if you live in a rural area, as an ADSL connection will be impossible if there is no CO near you.
